You use your blade to make a lever near the border of the door, and use all your strength to hold it... They are fast, and run away from the gargoyles before they can rend their flesh.

When the last of your allies crosses the door, you release it, and the door makes a huge sound of stone grinding.

You run away together with the loot, and after a few days, you claim your reward from the wizard.

The same day, the wizard uses the crystals to cast a spell for the Noble Lord and in exchange, he let the wizard use a small stone with the shape of a cube.

The portal opens with a flash of light, and you leave.
You are on the other side of the portal, and it closes...

You are in your city. The noises, the smells... the nightmare is over.

Years later, you have a normal life. And the adventure in the other world is just a bad dream...

You have a long, happy life!
